Neem Natural Mosquito Repellent

Is neem oil really 100% effective as a natural mosquito repellant? Let's look at the research...

Neem's natural mosquito repellent properties are an important weapon in the fight against malaria in third world countries.

Malaria is a big problem in tropical regions, and that is where neem grows best.

Neem is widely established so it is easily available and—most importantly—it works.

You have two main options for using neem oil to repel mosquitoes naturally:

You can use neem as a personal mosquito repellant (product link) on the skin, or you can burn it, for example as incense, or by adding neem oil to citronella flares or kerosene lamps.

Research on neem as a natural mosquito repellant plant

Here are results of some of the field studies that were done on the natural mosquito repelling action of neem oil:

In 1994 the the Malaria Research Centre of Delhi, India, tested whether kerosene lamps with 1% neem oil
can protect people from mosquito bites. For that test they burned the
lamps in living rooms, and from 6 pm to 6 am caught the mosquitoes
sitting on the walls and those attracted to human bait (i.e.
volunteers).

Neem oil clearly reduced the number of bites on the volunteers and also the number of mosquitoes caught. The protection was greater against anopheles species (the ones that transmit malaria) than against culex.

A 1995 study at a field station the Malaria Research Centre in Ranipur, Hardwar, India, tested a mix of 2% neem oil mixed in coconut oil.

They showed that applying that mixture to the skin provided significant protection from various mosquitoes. It worked best against anophelines, offering 96-100%
protection! (The malaria transmitting anopheles mosquitoes fall into
this group). The numbers for other species were 85% for Aedes (carries
dengue fever), 61-94% for Culex spp. (can carry West Nile virus) and 35%
for Armigeres.

In 1996 the Malaria Research Centre of Delhi, India did another field trial with kerosene lamps in an Indian village. Kerosene lamps with 1% neem oil were kept burning from dusk to dawn in living rooms.

They found that the lamps kept the mosquitoes out
of the living rooms and that the malaria incidents of the population
dropped dramatically (from about ten cases per thousand people to only
one in thousand). Once the lamps were removed, the mosquitoes returned
and so did the malaria.

(As for the safety of this method, another 1996 study by the Malaria
Research Centre in Delhi, India tested the effects of kerosene lamps
with 1% neem oil. Clinical examination of 156 adults and 110 children
did not reveal any major adverse effects after one year of exposure to
1% neem oil.)

What does it all mean? Is neem oil an effective natural mosquito repellent?

Well, it depends what species of mosquito you are dealing with. For malaria protection neem oil is fantastic. If you combine
the 96-100% protection rate of the home made mosquito repellent with
burning some neem oil when sitting outside and wearing sensible clothing, you are well protected indeed.

But take for example the common house mosquitoes in northern America.
They are a culex species, and neem's effectiveness against culex
varies. The number of bites will be greatly reduced, but you probably
still get bitten.

So to make an educated guess how effective neem oil will be, it helps
to know what mosquito species are common in your area or in the area
you want to visit. There are many different kinds of mosquitoes and they
are specific to different regions.

Another way to determine how well neem oil works for you as a natural mosquito repellent is to simply try it out.

And now to one important caveat. The only studies that showed
significant protection from mosquito bites through neem oil, were those
that used the neem oil in coconut oil mix. Rubbing pure oil on your skin
is not the most pleasant sensation in hot an humid climates where
mosquitoes are most active. Oh, and neem oil does not smell of roses!

But realistically these sprays do not offer quite the protection that you
would get from a neem oil/coconut oil mix. You can not expect them to perform like a
DEET containing mosquito repellent. Also, just like other natural
repellents those neem sprays need to be applied frequently whereas
DEET lasts for many hours.

Natural mosquito repellents do work. I use only natural mosquito
repellent, and I prefer those containing neem because of the many other beneficial effects it has. For most of the year and
around my house the amount of protection those natural mosquito
repellents offer is more than good enough.

But there are times of the year where
the mosquitoes are REALLY thick. (I live
in a tropical area.) During those times I make sure I also cover up
from head to toe, avoid the wettest and most overgrown areas in the
garden and avoid being outside at dusk and dawn. I will still not put
any DEET on my skin. That stuff in my opinion is far too toxic to use it
regularly.

Don't count on neem natural mosquito repellent to perform a miracle. But use it right (i.e. using the coconut oil/neem oil
mix, or using a spray and applying it regularly, and also burning neem in a lamp, candle or flare) and combine that
with other common sense measures, like covering up and using mosquito
netting, and there really is no need to put DEET on your skin.
